    Depends on the solar panels.

    The larger 20 watts or more panels that are used for highway camera battery and network connectivity systems or the ones on people's home roofs (100 watts or more each panel) are very reliable. These, like any other quality electronics still do need some attention with maintenance... like removing dust/dirt, so sunlight is not "filtered". They usually don't fail - but there are reasons they can be caused to fail... like getting hit with large hail stones.

    The smaller panels - less than 7 watts, typically used with inexpensive string lights or built in to low-cost, low voltage, battery banks or associated with certain toys, are not designed to be "rugged" or last multiple years and can fail under lots of different conditions. Most times, it is not the small panel that failed, but the device to which it is connected...

    More reliable than most electronics you can buy now.

    But sunlight or daily solar insolation is unreliable. Land area is also a constraint. Typical modules, which could measure approximately an area of 1m x 2m =2sq.m, will be rated from as low as 75 W to as high as 350 W, depending on their efficiency. Solar panel conversion efficiency, typically in the 20% range, is reduced by dust, grime, pollen, and other particulates that accumulate on the solar panel. They have to withstand damage by rain, hail, heavy snow load, and cycles of heat and cold. Paying to have solar panels cleaned is often not a good investment. Solar photovoltaic systems (solar PV systems) are often made of solar PV panels (modules) and inverter (changing DC to AC). The process of producing solar PV cells (computer chips) is energy intensive and involves highly poisonous and environmental toxic chemicals. Potential induced degradation (also called PID) is a potential induced performance degradation in crystalline photovoltaic modules, caused by so-called stray currents. This effect may cause power loss of up to 30%.

    When electric networks are down, solar panels are often insufficient to fully provide power to a house or other structure, because they are designed to supply power to the grid, not directly to homes.

    PV is a promising option for reducing energy charge when electricity price is reasonably high and continuously increasing. However for sites with peak demand charge in place, PV may be less attractive if peak demands mostly occur in the late afternoon to early evening, for example residential communities.

    Floating solar panel has serious advantages compared to ground-mounted systems. The costs for a floating system are 20-25% higher than for ground-mounted systems. Serious advantages of floating units are no land occupancy, reducing evaporative loss of water from water bodies, easy to install or decommission and allow vertical axis tracking to gain upto 25% more energy

    yes. The only issue is having the money up front to put in solar panels. You can save more then 70% on electric bills. each month. Say the average bill is $100. you can save $70 a month every month during the hot months and cold months. and in spring and fall months you might even have extra electricity. So you can save $700-$900 a year. But it will cost $2000-$2800 to put in solar panels. it would take 3 year to pay for the panels. It is usually worth it. Just not everyone has $2500 to put in solar panels.

    Solar panels are very reliable. They have no moving parts and don't tend to "break". They have a long life span with slow degradation.

    The solar power systems can have problems and be more complex. I live fully with solar power and there can be issues with fuses blowing or if you have a non-pure sine wave inverter (I do) then some devices will not work.

    But a well designed solar power system is very reliable and without the monthly payment to a centralized utility.

    View this - - and you can see that some of the best electronics companies on the planet are behind the assembling of solar panels. That is not necessarily a marker of simplicity, however the moderately simple design and assembling of solar panels means they don't have any moving or mechanical parts - something that doesn't move is bound to be reliable.The oldest solar panel, as a matter of fact simple, the solar panel still works following 60 years - Inhabitat - Green Design, Innovation, Architecture, Green Building - so yes, they are truly reliable.

    Yes but expensive I've heard.
